Urgente!! É pra Hj, mt obg a quem responder

Answer 1

A)(3x+5)2 = 6x + 10 = 0  
  6x = -10
  x = -10/6
  x = 5/3

B)(abc-8)2 =
 2abc - 16 = 0
 2abc = 16
abc = 16/2
 abc = 8

C)(1+x2)2  
 2 + 4x = 0 
 4x = -2
  x = -2/4
  x= -1/2

D(x/2+5)2 
  2x/2 + 10 = 0
  x + 10 = 0
  x = - 10

E)(x+10)2
    2x +20 = 0
    2x = -20
    x = -20/2
    x = -10

F)(2x-3)2
    4x - 6 = 0
    4x = 6
    x= 6/4
    x = 3/2

G)(3ab-5)2
     6ab - 10 = 0
     6ab = 10
     ab = 10/6
     ab = 5/3

H)(4x-3y3)2
     8x - 18y = 0

I)(x-3)2
2x - 6 = 0
2x = 6
x = 3

J)(6x5+4)
30x +4 = 0
30x = -4
x = -4/30
x= -2/15
